SEAT ATTACHMENT Fon M oToR VEHICLES.

Application filed August 23, 1921. Serial Ito-.494,637l

T o all whom tma'y concern; Be it known that I, JOSEPH A. TnUEs- DELL, a citizen of the United States, residing at South Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Seat Attachments for Mo-tor Vehicles, of which the following is a Specification.

T he present invention consists of a seat attachment designed especially for application to the ats of motor vehicles.

Objects of the invention are to lprovide an attachment of this nature which will support an occupant in spaced relation to the seat thereby permitting free .circulation of air between the seat and occupant; to provide a support. which is constructed to conform to the curvatures of the body to thereby retain the occupant from lateral displacement; to provide a device of Simp-ley construction which may be quickly and conveniently assoclated with the seat; and to provide a collapsible support of this nat-ure which may be folded together to occupy a minimum amount of space when not in use. y. l

Other objects of the invention will be partly described and partly apparent from the following description of the present form of the invention taken in connection with the accompanying drawings wherein F ig. 1 is a side elevational view of an attachment constructed in accordance w-ith thls invention illustrating its application.;v

Fig. 2 is a rear elevation of. theback portion of the attachment; l

Fig. 3 is a top plan view of the attachment per se; i

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2 looking in the direction of the arrow; and

Fig. 5 is a perspective view of the frame or skeleton used in the present invention.

In the drawin in order to illustrate-the application of this invention a portion of a motor vehicle seat body, generally designated 6 is provided. The back of the body is upholsteredand bulged outwardly as indicated at 7, in a manner well lmown in the art.

` Moreover, the back is provided with an un- The device of this invention consists of a skeleton frame generally designated 10, as illustrated to advantage in ig. 5. frame consists of two parallel side bars' l11 the lower terminals of which Vare bent into a substantially U-shape to provide seat receiving arms 12. These arms are engaged in The the recess 8 and embrace the seat 9 as shown in Fig. 1. The bars 11 are connected by rods 13 of concavo convex configuration, the conveX faces thereof being engaged with the back 7 of the seat body. In this way the end bars 11 are retained in spaced relation to the back 7. The portion of the skeleton above described comprises the back of the seat attachment and has hinged thereto a bottom portion consisting of side or end bars 14 which are connected by concavo convex rods `15. The convex faces of said rods 15 are engaged with the top of the seat 9 thereby retaining the bars 14 spaced from the latter. The rear ends of said bars 14 are looped 'around the lowermost of the rods 13, as indicate-d at 16. In this way the bottom portion of the skeleton may be folded into engagement with the back portion of the skeleton so that the attachment will occupy a minimum amount of space when not in use. A flexible covering is mounted over the back of the skeleton likewise a Separate covering over the bot-tom of the skeleton. The covering used for the back and bottom of the skeleton is identical, consequently, a description of one will suffice for a complete understanding of this portion of the invention. The preferred covering at the present time consists lof a fabric blank 17 having the necessary integrity to withstand the pressure blank are folded over the bars 11, in covering the back of the skeleton, and preferably are equipped with straps 1.8 which are adjustable to permit the covering to be secured to the skeleton. When arranged in this' way the covering rwill be spaced from the concave faces of the rods'13, as shown to advantage in Fig. 4. AIn this way the covering will slightly flex under pressure exerted thereon by the occupant of the vehicle. In the same way the covering is spaced from the con-v cave faces of the rods 15 to be sldably fiexed under the weight of the occupant. The fabric is provided with a plurality of eyelets 18 to permit free circulation of air through the attachment as Well as between the latter and the seat. i

The attachment when constructed in accordance with this invention, as above outlined, and applied to the motor vehicle will support an occupant of the vehicle-in spaced relation to the seat permitting free circulation of air between the seat land occupant thereby increasing the comfort of the motorist, especially the operator of the vehicle who is compelled to maintain practically the same position at all times. The skeleton frame conforms substantially to the curvatures of the body. Consequently, the frame Acovering will flex. slightly inv correspondence to said curvatures under weight of the occupant; Therefore, lateral displacement of the occupant of the vehicle is curtailed and a very desirableyieldable seat and back .rest

provided. It is of course to be understood that I have above described merely the crux of my invention without attempting to illustrate features of ornamentation or the like which may-be added thereto within the scope cluding a skeleton -fraxne for engagement' with the back of the seat and comprising upright bars connected by concavo convex rods the convex sides of which latter en age the seat back to space saidupright bars rom-the latter, the lower ends of said bars. being extended to lie beneath theseat proper and being shaped to snugly embrace the latter, a

perforate covering stretched around said frame to engage said upright bars and being spaced from the concave sides of said concavo convex rods, a second frame including side vrods pivotally connected to one of the concavo convex rods of the first said frame,

and concavo convex rods connecting said side rods and havin their convex' faces engage with the to o the seat roper.
